Abstract: An apparatus feeds raw material bars to a furnace body of a melting furnace, and includes an enclosure body provided with a vertical feed passage to be disposed above an open top side of the furnace body. A feeding unit includes a push mechanism extending into an upper part of the feed passage, and a material retarder extending into a lower part of the feed passage. A transferring unit transfers a raw material bar to the feed passage in a manner that the raw material bar extends vertically in the feed passage. The push mechanism pushes the raw material bar in the feed passage downwardly, and the material retarder retards downward movement of the raw material bar out of the feed passage and into the furnace body.

Abstract: A directional solidification furnace includes one or more movable cooling plates disposed beneath a crucible. In a first position, the cooling plates are free from contact with a crucible support positioned adjacent the crucible. In a second position, the cooling plates are in contact with the crucible support. A control system is used to control the amount of force exerted by the cooling plates against the crucible.

Abstract: A method is provided for the pyrolysis or thermolysis of a fluid or fluidized starting material in a tube bundle reactor including a plurality of heatable reactor tubes. The method includes feeding the starting material to the tube bundle reactor at one end by at least one supply line; wherein the supply line has several pressure reduction units which enable a positive pressure before the starting material is introduced into individual reactor tubes of the tube bundle reactor and a negative pressure inside the reactor tubes. The pressure reduction units control a substantially equal inflow of the starting material into individual reactor tubes and the reactor tubes are heated to a decomposition temperature of the starting material in at least one primary section. The starting material is pyrolyzed or thermolyzed and a pyrolysis or thermolysis product is obtained.

Abstract: A permanent magnet air heater has a housing with an internal chamber accommodating an electric motor rotating a fan to move air through the housing. A non-ferrous member having bores for cylindrical magnets and a steel member with a copper plate secured to the steel member are rotated relative to each other by the motor whereby the magnetic field between the magnets and copper plate generates heat which is transferred to air in the housing moving through the housing by the fan.

Abstract: An apparatus for thermally treating and coloring a plurality of curved suture needles. The apparatus includes a conveyer for transferring the plurality of curved suture needles from a source of curved suture needles to a receiver, a housing positioned adjacent the conveyer, the housing having a first end, a second end, and an opening running from the first end to the second end, the opening aligned with the conveyer to enable the plurality of curved suture needles to pass therethrough, a heat source located within the housing for heating the plurality of curved suture needles as the plurality of curved suture needles are transferred by the conveyer from the first end of the housing to the second end of the housing and a system for providing a gas mixture containing a fractional concentration of oxygen to oxidize and colorize the surfaces of the plurality of curved suture needles as the plurality of suture needles pass through the housing.

Abstract: The present invention relates to an expansion system using a plasma discharge in which in which a charged electric energy is fast discharged, so that a high pressure is generated within liquid based on an impact wave, which can be used in various industrial fields as a simple expanding method. The expansion system using a plasma discharge comprises a capsule for sealingly storing a certain liquid therein; a cable of which one end is connected with an expansion wire within a liquid of the capsule, and other end is connected to the outside of the capsule; and a controller that converts an external AC power inputted through a terminal into a DC power and indicates the power on a lamp and a voltage meter and applies a high voltage energy to the cable in cooperation with an operation of the push button, wherein an expansion is instantly achieved in the interior of the liquid.

Abstract: A coil/capacitor combination useable as an induction furnace includes a reactive capacitor bank directly bolted to the coil and protected from coil fields by shields and heat sink plates. The coil includes a selectively openable switch for placing the coil assembly on and off of a moving strip. The switch is operated by deflecting coil turns within the natural resiliency of the turns themselves.

Abstract: A heating machine for heating an ingot of a metal such as a magnesium alloy. The heating machine has a heating chamber equipped with a RF induction coil capable of swinging about a horizontally axis. The coil is placed horizontally, and the metal ingot is fed into the coil from an introduction chamber by a pushrod. Stoppers prevent the ingot from falling from the RF induction coil when it is switched from its horizontal posture to its vertical posture. The coil is wound on a cylindrical member. A rotatable hollow shaft is firmly mounted to the holder in a perpendicular relation to a substantially axially central portion of the cylindrical member. A part of the coil is inserted in the hollow shaft via an insulating material. The rotatable hollow shaft is swung by a swinging mechanism. The induction heating coil is wound on a ceramic holder. A metal ingot is inserted in the holder with a given clearance.
